hey all
ive been following this topic for a while now and thought i'd give my two cents worth. i build and drift RC cars so i have a pretty good idea on small scale motors and electronics. I've been playing with a few ideas and from what i can see both in wheel and external motors can be done!
i think an in wheel would be the way to go, as for power supply there are small rc batteries in the lipo range which pump out some great power with the right motor, but seeing that we need alot of power i reckon you should check out drill batteries, my cordless drill i use at work uses 18V batt's which can be easily modded to fit on the blades.

it says there i the goldenmotor site that"The pancake motors can be widely used as the driving hub on electric bicycles, scooters, tricycles, battery powered vehicles and industrial motion solutions"it means its strong enough,and about le wheel motor its very hard to contact him!!!
and looks like he doesn't want to cooperate with us 🙁

@tokuin
are you saying that we have to normally skate to accelerate at starting point ?? COOL!!!!it means if we race our speed wouldn't depend on our air trek it depends on how we accelerate! 😃

@ranio
please work on the battery...
so...............how much bolt is the batt your talking about??and also the ampheres??

The drill battery is a 18 volt lithium-ion at 3.0Ah which is a 10 cell battery, can get it in 5 cell but at 1.5Ah.
as for the RC battery ive seen some lipo's at 22.2 volts 5000mAh that has about 200A burst current.

wow... I can see some progress =)

More practical, less theory

is that an air trek cosplay??
cool.......nice job 🤣

and looks like he doesn't want to cooperate with us sad Pancake motors of a large enough size can be used to power bikes. Shrinking them down to the size of a skate wheel will make a big difference.

It begs the question, if such powerful motors existed, why have companies & inventors produced products such as "ishoes" and "motosk8" when they could have made a much better product using these pancake motors? Surely they would have looked at all their options before spending thousands of dollars to sell an inferior product?

thats most likely because they wanted the easy cost efficient way. with motosk8 it looks like they wanted more power that lasts longer so they went with a gas powered machine. As for ishoes, i don't think that's even a product, i think its just a project that someone worked on by themselves, they didn't use inline skates so they probably never thought about in-wheel motors. As for the power that these little motors have, i suggest u go on the goldenmotor website and check them out. The strongest motor that they make has 500w output, its not as powerful as the le wheelmotor, but if we tweak it we should get some good results. Plus since we will have two motors pushing us we should be fine. It would be awesome if we could get teamtestbot in on this but it doesn't look like they want anything to do with us.

i dont see a problem with the motors, 2 motors per skate will half the work for each foot. it sounds like you want a powerful motor to get you going from a stand still? am i right? if your using your legs to get you going, then the motor already moving and only has to use power to go faster, this will save battery life. this initial power a motor needs to get something moving is a lot more then just speeding something up that's already got momentum.

your wrong actually, my point was (i mentioned this on the last page) that u don't need to start from 0, in fact that was also brought up on this page by mcblaise. But yeah your exactly right, what we need to focus on isn't really the power output of the motor but the max rpm that it can reach.

ok, if we went for in internal motor, whats the max size (in mm) motor that will fit in a wheel? (or preferred motor) ill have a look at what i can find for power supply.

well i would say 3-4" would be the maximum cause we wouldnt want a wheel bigger than 5", i contacted a few companies but i only got a reply from one, but i asked if they could make wheel motors with a diameter of 5" or less. If i get a reply i'll post it here. As for power supplies, it would depend on the motor, some require 48v power supplies so for that we would have no choice but to go with a backpack battery.

thank tokuin ^^ i read the last few pages now.

i like the self acceleration idea to start up. i agree with that 100%

how heavy are the batteries?
the heavier the person is, the harder it is for the motors to work.

depends on the motor, its hard to pick a battery to suit the job if we dont know what we need. what motor would be a good starting point? we can always change the motor in something better comes along.

i supose your right =D

i guess the main problem is getting the prototype motor right for the job. 😐

we dont need a 'the' motor, we just need something so we have a starting point
